I have some kind of innate deep fear/repulsion against birds and especially flocks. Watching this massive group of little winged velociraptors taking off some kind of poplar tree—there are so many that the tree is deformed by their weight—is my idea of hell.

Flock, a new iPhone app from the people behind Bump, solves the first world problem of having to send photos to your friends through e-mail by creating shared photo albums with your friends with pictures that have similar metadata. It works like magic.
